我正在尝试使用以下包添加 cosmosdb 文档：

https://github.com/Elfocrash/Cosmonaut

api控制器是这样的：

  [HttpPut]
        public async Task<IHttpActionResult> PutTenant([ModelBinder(typeof(TenantModelBinder))] Tenant tenant)
        {
            //var provider = new MultipartMemoryStreamProvider();
            //var contentType = "";
            //var content = new byte[0];
            //await base.Request.Content.ReadAsMultipartAsync(provider);
            //if (provider.Contents.Count > 0)
            //{
            //    contentType = provider.Contents[0].Headers.ContentType.MediaType;
            //    content = await provider.Contents[0].ReadAsByteArrayAsync();
            //}


            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["AzureStorageKey"].ToString());
            // Create the blob client.
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

            // Retrieve reference to a previously created container.
            CloudBlobContainer container = blobClient.GetContainerReference(ConfigurationManager.AppSettings["certificatesContainer"].ToString());

            // Retrieve reference to a blob named "myblob".
            CloudBlockBlob blockBlob = container.GetBlockBlobReference("myblob");

            // Create or overwrite the "myblob" blob with contents from a local file.
            //blockBlob.Properties.ContentType = tenant.ContentType;
            MemoryStream stream = new MemoryStream(tenant.CertificateFile);
            blockBlob.UploadFromStream(stream);

            var tenantStore = CosmosStoreFactory.CreateForEntity<Tenant>();
            tenant.CertificatePath = blockBlob.Uri;

            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

            var added = await tenantStore.AddAsync(tenant);
            return StatusCode(HttpStatusCode.NoContent); 
        }

但是我收到此错误：

Unable to resolve iD for entity of type Tenant

我的租户类：

  public class Tenant
    {
        public string TenantId { get; set; }
        public string TenantUrl { get; set; }
        public Uri CertificatePath { get; set; }
        public string CertificatePassword { get; set; }

        public byte[] CertificateFile { get; set; }

        public override string ToString()
        {
            return JsonConvert.SerializeObject(this);
        }
    }

正如 Github 自述文件页面中的限制部分所述

由于 Cosmosdb 的内部 id 属性的工作方式，存在强制性限制。如果没有字符串，则不能拥有名为 Id 的属性或具有属性 [JsonProperty("id")] 的属性。cosmos id 需要以某种方式存在于您的实体模型中。因此，如果它不是您的实体的一部分，您可以只实现 ICosmosEntity 接口或扩展 CosmosEntity 类。

TenantId在您的情况下，推荐的修复方法是使用[JsonProperty("id")]属性来装饰。
